About Me


My name is Brandon. I like video games and computers. My favorite game is Fallout 3. I live in a brick house on a brick road.

Leaf Questions

1. Staghorn Sumac

2. Rhus typhina

3. Caterpillars infect the trees.

4. It provides food for the ruffed grouse.

5. It is in the anacardioideae or sumac family. It is similar to the other plants in that family because it grows fruit and also has the same general type of leaf.

6. It is mostly used for landscaping and also to make jelly.

7. The Twig grows a fur during winter.

8. The is found mostly in the U.S. and is native to Pennsylvania.

Barley




2. It is an ingredient in bread, biscuits, traditional beremeal bannock, soups, stews, alcoholic drinks, and animal feed.

3. Barley is a member of the grass family. In England, barley straw is put in mesh bags and floated in fishponds to help reduce algal growth without harming pond plants and animals.

I got all my information from http://en.wikipedia.org/wiki/Barley.

2. In the potato with the salt water, the water went out of the potato because the salt dehydrated the potato. With the potato in the regular water, the water went into the potato and made it more stiff. Finally, with the sausage, the iodine went into the cornstarch solution.

3. The potato with the salt water demonstrates diffusion while the one with regular water demonstrates osmosis. Also, the sausage demonstrated osmosis.


DNA Replication Model Project


Key:

Stand 1 on left and Strand 2 on right

The DNA starts out as a helix.

Step 1: The DNA Strands unwind.

Step 2: Then the hydrogen bonds start to break

Steps 3-4: Now Strand 1 gets a new strand 2 and Strand 2 gets a strand 1

Step 5: Finally, the hydrogen bonds reform

Telomeres- Long stretches at the ends of the chromosome

Okazaki- A section of complementary strand

Fragments- Parts of a strand

DNA Ligase- Stitches the Okazaki fragments together

Telomerase- An enzyme that adds telomere repeat sequences to the 3’ end of DNA strands

Cancer- Arise from somatic cells. Most regain the ability to synthesize high levels of telomerase throughout the cell cycle, and thus are able to prevent further shortening of their telomeres.

Transplanted Cells- Gene therapy that removes cells, transforms them with the gene for the product that the patient has been unable to synthesize, then return them to the patient.

Cloning- taking a nucleus taken from a cell and growing a replica of the animal.

Aging- When getting older, cells do not divide as much.
